[Newbies] Entering the caret (^) in Squeak on Linux

Hello,

any ideas? I've tested the stable Squeak release on Ubuntu 18.04 and
Fedora 28 and I can't enter the caret on both systems...

Any hints are welcome :-)

Hello,
I can't enter the caret character (^) in Squeak 5.1 on Linux 32bit.
I'm pretty sure that it worked some versions ago.
I also noticed that Squeak is not able to print non-ASCII characters
(like €), it instead displays just a question mark.
Is this a default setting? How do I enter the caret?
Thanks and have a nice week,
Marc

Hi Christian,

I've configured my keyboard with 'deadkeys' (I need the caret for
Esperanto characters like ĝĥ), so I already tried "^ + Space", but it
justs displays a questionmark.
When I switch to 'nodeadkeys' I can enter the caret. So this is solved
for now ;-)

But I'm still wondering, why I can't type UTF8-characters? I thought
Squeak is UTF-8 aware?

Thanks and best regards,
Marc

On some system (depending on your layout config) the caret is a
dead key, that is, it will not get displayed when pressed once,
but hold as a modifier for entering keys like ấ (which can be
produced with ^ + a). Try typing ^ + space and see whether the caret
appears. If that get's too annoying try configuring a 'nodeadkeys'
variant in your keyboard layout preferences on your linux system.

Well, the question mark is just Squeaks way of saying "i know the Character but I don't have it in the font"

you can do the following:

put a $ before the character, select the whole thin and hit ctrl-i. Then you see what character it is, typically by unicode point.

PS: I'd be very interested what ^+space produces for character :)

Thans Tobias,

I did now the following in the Workspace:

I entered "^ ", Workspace displayed: " ?",
I entered "^g", Workspace displayed: "g?"

Putting the $ before the ? and inspecting the character just displays
the same character again, for example self has the value "$?" in the
inspector... no unicode point, just the questionmark... ;-)

Best regards,
Marc

Ok, it should actually look somewhat like this when you hit 'ctrl-i':

In any case, '$i codePoint' (with i being your strange character) should work...

Hello Marc

You write:

I entered "^ ", Workspace displayed: " ?",
I entered "^g", Workspace displayed: "g?"

In case you have problems getting what Tobias suggests to work it
might be easier to evaluate (i.e. select and choose 'do it')

' ?' inspect
'g?' inspect

Regards

Hannes

In any case, '$i codePoint' (with i being your strange character) should work...

Hello Tobias, hello Hannes,

Strange, my inspector window does not show the code in its title, but
printing the codepoint of the questionmark shows me the value '770',
which is the "COMBINING CIRCUMFLEX ACCENT"
(http://www.codetable.net/decimal/770) whereas the correct caret has
the value '94', which is "CIRCUMFLEX ACCENT"
(http://www.codetable.net/decimal/94) - which somehow makes sense ;-)
So it seems to be an issue with the input system, not with Squeak.
Although I'm really wondering how I can acces the "CIRCUMFLEX ACCENT"
with the 'deadkeys' keyboard layout...

Thanks for your help,
Marc

Ha, I figured it out: with 'deadkeys' keyboard settings I have to
enter the caret twice (^^) to get the correct "Circumflex Accent"!

This might still be a Squeak bug:

(String withAll: (#($a 770) collect: #asCharacter)) composeAccents
==> 'Ã¢'

It works with $a so should space work too? I'm not entirely sure of the
Unicode normalization rules.
